might look into the stuff they use for boat molds.
also, cultural marble molds are coated with what looks like gelcoat over
wood that they wax before pouring the marble chips and epoxy? slurry/mix
into.

: Hi Group,

For plaster casting (gypsum, plaster of Paris), I've used tincture of
green soap.
Teflon requires very high heat in the process and the coating is baked on.
Something like 500 degrees for each of two or more coats. Not suitable for
wood.
You may want to consider spraying with silicone after every so many uses.
Silicone spray is often used as a mold release, but here are others
available. None are permanent that I'm aware of.

it mostly depends on what won't react with the material you are
molding.

How would you get a "non-stick" coating to stick to the moulds? If it
sticks, then it isn't doing its job...
Then use a mold release (usually silicone-based) to spray into the
mould. (available at hobby shops under different brand names...)
You apply the mould-release each time you use the mould.
A thin coat of Vaseline also works well, but it depends on what you
using the mould for.
If you want a true non-stick mould, you shouldn't be using wood. You
should be making the mould out of an RTV silicone that is designed for
mould-making.
